Notice (Rating)
In operating temperatures exceeding +85D, derating of
current is necessary for chip Ferrite Beads for which rated
current is 1500mA or over. Please apply the derating curve
shown in chart according to the operating temperature.

!Caution/Notice
!Caution
(Rating)
Do not use products beyond the rated current and
rated voltage as this may create excessive heat
and deteriorate the insulation resistance.
Notice
Solderability of Tin plating termination chip might be
deteriorated when low temperature soldering profile
where peak solder temperature is below the Tin melting
point is used. Please confirm the solderability of Tin
plating termination chip before use.
